✓ A rare case is reported in which a symptomatic Rathke's cleft cyst was studied by light and electron microscopy and tissue culture. The findings are compared with those of a craniopharyngioma studied in the same way. The patient was a 26-year-old woman presenting with headache, chiasmatic syndrome, and hypopituitarism. A cyst containing a mural nodule was partially removed and an Ommaya reservoir placed in the operative site for further treatment. The cyst wall was composed of connective tissue and three kinds of epithelial cells: non-ciliated squamous, ciliated columnar, and mucous-secreting cells. The morphology of these cells in vitro was similar to prickle cells seen in craniopharyngioma and the epidermis. It is concluded that both Rathke's left cyst and craniopharyngioma originate in remnants of Rathke's pouch, but at times may show some histological differences.

✓ An abscessed Rathke's cleft cyst was removed in a 50-year-old woman who had had headaches and episodic fever for 3 years and had been on intermittent methotrexate therapy for psoriasis for 4 years. There was clinical and laboratory evidence of panhypopituitarism. Erosion of the sella turcica was present. The patient has remained asymptomatic on replacement therapy. A brief review of abscess formation in the region of the pituitary gland is presented.

The induction of melanization in xanthic goldfish scales with ACTH in vitro has been studied by light and electron microscopy utilizing ammoniated silver nitrate staining of premelanin and melanin. The melanized cells (melanophores and melanocytes) and the yellow pigmented cells (lipophores and the newly described lipocytes) were found to possess many similarities at the levels of cellular and subcellular structure. The latter cells contain characteristic cytoplasmic bodies which react positively to the premelanin stain. Changes accompanying ACTH stimulation of goldfish scales in tissue culture suggest that these bodies in the lipocytes and lipophores can become melanized. Electron micrographs illustrate the intermediate staining of newly formed melanin granules in an induced melanocyte and the appearance of a transitional melanolipophore. It is postulated that ACTH can promote the association of the enzyme tyrosinase with the preformed structure of unmelanized granules.

✓ A 5-year experience with the glutaraldehyde-stabilized freeze-dried radiation-sterilized calf pericardium used as a dural substitute is reported. The structure of pericardium xenograft is compared with other collagenous materials used for duraplasty (allogeneic fascia lata and dura mater) by light and electron microscopy. The special neurosurgical techniques involved in using pericardium xenografts in the reconstruction of suboccipital dura mater in children are presented in detail.

✓ The authors encountered a case of chronic subdural hematoma of which the subdural neomembrane (SN) showed numerous spindle-shaped cells identified as smooth-muscle cells (SMC's) by electron microscopy. On reexamination of 214 cases from the files, SMC's were found with light microscopy in seven cases. In these cases, the SN was well organized (collagenized). In three additional cases examined with both light and electron microscopy, SMC's were not apparent with light microscopy. However, in all cases, cells with ultrastructural features of both fibroblasts and SMC's were observed. Well formed SMC's were found in two additional cases of well organized membrane. Based on these observations, it is concluded that the presence of SMC's in the SN is not a rare phenomenon. The possible origin of SMC's in the SN and their pathological significance to the organizing process of chronic subdural hematoma are discussed.

✓ A prolactin-secreting pituitary adenoma containing amyloid substance was studied by light and electron microscopy. The tumor was found in a 32-year-old woman who presented with a short history of amenorrhea and galactorrhea. Pituitary adenoma containing amyloid substance is a very rare entity, and the implications of this association are discussed. Previous reports, suggesting that mesenchymal cells or hormone-secreting tumor cells in pituitary adenomas produce amyloid substances, are reviewed.

The occurrence of symptomatic Rathke's cleft cyst (RCC) apoplexy is extremely rare. This is often misdiagnosed due to similar presentations to subarachnoid haemorrhage and pituitary apoplexy. This case highlights an excellent example of similar clinical presentation and serves as a learning case for clinicians. A 40-year-old lady presented to a district hospital with 9 days of worsening severe headache associated with blurring of vision, photophobia, stiff neck, nausea and vomiting. Nuchal rigidity and Brudzinski’s positive. Blood test showed hyponatremia, raised inflammatory markers and normal dynamic pituitary function test. CT Head demonstrated no evidence of space-occupying lesion or intracranial haemorrhage. Lumbar puncture showed xanthochromia positive consistent with subarachnoid haemorrhage. MRI head advised by Neurosurgery team and revealed a focal lesion involving anterior pituitary macroadenoma with mass effect on optic chiasm with possible haemorrhage within. Further assessment in tertiary hospital confirmed loss of visual acuity and field deficit. Patient underwent emergency endoscopic transnasal transsphenoidal resection of apoplectic tumour and repair of CSF leak with graft from thigh. Histopathology report showed a Rathke’s cleft cyst with squamous metaplasia. Post operatively, the patient developed sinusitis which fully recovered, and MRI showed good decompression. The author demonstrated a rare case of symptomatic RCC which was initially presumed to be pituitary apoplexy. Radiology imaging and treatment approach for both conditions are quite similar and can only be differentiated by histopathology. Further research is required to identify the causes and risk factors of RCC apoplexy to aid early detection and diagnosis.International Journal of Human and Health Sciences Supplementary Issue-2: 2021 Page: S23
